Hi Tony,
You can most likely use what ever url you like :). The last example
below (named paramters) is native to cake 1.2 but you can do it quite
easily with cake 1.1.7:
Assuming controller modules and action show, you can use any of the
following:
Modules/Show?level=2&parentLevelId=24&levelId=44
Modules/Show/2/24/44
Modules/Show/level/2/parentlevel/24/LevelID/44 <- with some custom
code. A bit fragile.
Modules/Show/level:2/parent:24/LevelID:44
Or any other permutation you can think of (probably).
You could put a simple beforeDelete method in your model to take care
your your parent problem, I don´t think you would need a parentLevelID
field in your module - that would be in the level model. Self joins
aren´t an issue.
Regarding the different foreign keys, see
http://manual.cakephp.org/chapter/models. If the key isn´t following
convention - you simply override it in the association defenition and
"that's that".
HTH,
AD7six
